  • Test review: BAADER ULTRA NARROWBAND FILTER, Francesco di Biase

      Mr. Francesco di Biase had the opportunity to test the new Baader Ultra Narrowband Filters 36mm in unmounted version in his small observatory with a sliding roof under a suburban sky (19.40 SQM). Among other things, the observatory is equipped with a 10micron GM2000 HPS II mount and a 12" GSO RC telescope, which he uses at full focal length with a KAI 4022 CCD sensor. We are very pleased about the positive feedback on the new CMOS-optimized Baader 3.5 / 4nm Ultra-Narrowband Filter-Set – CMOS-optimized (H-alpha / O-III / S-II) (various versions available) and his field report. Original: My general opinion on performance, supported by the tests carried out and my experience with other high-end products, is fully positive. I believe that they can...
  • A report on visual use of the Baader H-Beta 5.5nm CMOS filter

    In the summer of 2021 I approached Baader Planetarium to ask whether I could test the new Baader O-III Narrowband-Filters (6.5nm) – CMOS-optimized (various versions available) to explore its visual capabilities for binocular observation of galactic nebulae. To my delight and surprise, Messrs. Baader offered not only to provide on loan the 6.5nm OIII Filter which I had requested, but also a prototype of the Baader H-Beta Narrowband-Filter (5.5nm) – CMOS-optimized (various versions available) now available on the market – and to do so in pairs in both 1.25” and 2” filter cells! I must admit that, initially, I had no particular expectations of the 5.5nm filter. For I, too, had allowed the prevailing myths about H-Beta obervation to cloud my view. These myths include:...
  • A compact and lightweight scope for guiding: QHYCCD's miniGuideScope

    A lot of people who undertake astrophotography, whether they are beginners or seasoned amateurs, opt for high quality small aperture, short-medium focal length telescopes such as BAADER APO 95/580 CaF2 Travel Companion (#2300095, € 4225,-) or the 8" Celestron Rowe-Ackermann Schmidt Astrograph. These telescopes will give a relatively wide field of view allowing images to be taken of spectacular large celestial objects such as the North American Nebula, Andromeda galaxy, Orion nebula, Pleiades open star cluster and many many more. Guiding is essential for taking long exposure images of such celestial objects. Long gone are the days when your guidescope was a telescope that would be similar in focal length as your imaging scope and you would guide by looking at a star through a...
  • NEW: Baader SunDancer II H-Alpha Filter – Test Review

    I was lucky enough to be able to "play" with one of the first SunDancer II H-alpha filters and see what it is capable of. Even though I am not one of the most experienced H-alpha observers, I have been able to observe the sun with the two H-alpha telescopes of the Observatory in Heilbronn/Neckar again and again for more than 20 years. These are a 20/20 H-alpha filter by Wolfgang Lille with 0.8Å on the 150/2250 refractor (which complements a classical prominence filter), and a Lunt LS-60 telescope. I freely admit that I find the concept of the Lunt convincing, especially for public observatories: a complete telescope with which nothing can go wrong. It's foolproof, which is especially important in an club where many...
  • Celestron CGX mount in combination with StarAid Revolution as guiding cam

    The CGX: A Versatile Mount For Everyone! Recently I was able to work with the Celestron CGX, the Baader Apo 95/560 Travel Companion, the Nikon D810A and the StarAid Revolution as guiding system for the first time. Once again the results proved how much you can get out of a good system if you take some time to tweak the settings a little bit instead of simply working with the factory settings of the software without taking a closer look at them. To get straight to the point: I'm really excited about what the CGX delivered last night! For polar alignment, I used the star Regulus and the integrated AllStar Polar Alignment (ASPA) system of the CGX. My alignment routine only consisted of a 2-star alignment, with...
  • The disc of Mercury near the upper conjunction, captured with the Baader APO Travel-Companion 95/580

    Our customer Jörg Schoppmeyer sent us this unusual picture: a circular Mercury, shortly after the upper conjunction and only 1.8° away from the Sun!     Mercury is traditionally a difficult object to observe. The reason: The small planet is always close to the Sun and can be seen with the naked eye only shortly after sunset or before sunrise when it is at maximum distance from the Sun. Legend has it that even the great astronomer Johannes Kepler never saw Mercury with his own eye - but Kepler did not have a modern telescope with accessories from Baader Planetarium... On August 18th, 2020, Jörg Schoppmeyer pointed his BAADER APO 95/580 CaF2 Travel Companion (#2300095, € 4225,-) at Mercury. Since the small planet was only...
  • 1st Light with the QHY600 EB: a first field report

    Darkness Became Light! ... A Quantum Leap in 36 x 24mm at 61.1MP? In recent years, color cameras have become increasingly popular. A reversal of the trend is not to be expected. One reason for this is the ability to capture weak structures in deep-sky objects even with moderate exposure times. Developments in CMOS sensors and recently the BSI sensor technology have played a decisive role in this. In addition, both quantum efficiency (QE) and full-well capacity increased, noise was reduced, pixels became smaller and smaller, and dynamics increased with almost every new sensor generation. What happens when all these developments see the light of the stars in a new camera like the QHY 600M with a black and white sensor? I had asked myself...
  • Field test of MaxBright® II Binoviewer by William A. Paolini

    William "Bill" Paolini has been actively involved in optics and amateur astronomy for more than 50 years, and is author of the popular book: : Choosing and Using Astronomical Eyepieces We appreciate the positive feedback we have received so far. The Baader MaxBright® II Binocular with case (#2456460, € 425,-) incorporates the knowledge aquired during thirty years of building astronomical binoviewers. It closes the gap between cheaper entry-level binoviewers and our high-end Mark V Giant Bino – see also the article about the differences between MaxBright® II and Mark V Großfeld (Giant) binocular. A detailed test report: Field Test of the Baader MaxBright® II Binoviewer has now been published by William Paolini in the most popular astro forums. We are very happy about his extremely...
  • The First Impression: RASA 8 With ATIK Horizon Colour Camera

    RASA 8 – The family is complete – First Impressions Here is a firsthand report by Christoph Kaltseis about his work with the RASA 8 and an ATIK Horizon colour camera. On the ATT fair I was asked by the company Baader if I'd like to test the newly announced RASA 8" - Rowe-Ackermann Schmidt Astrograph (#822252 € 2.195,-) . I've been using both the RASA 11" - Rowe-Ackermann Schmidt Astrograph (#822250, € 4495,-) and the larger RASA 36cm - Rowe-Ackermann Schmidt Astrograph (#822251) successfully for some time now. So I know the system of the Rowe-Ackermann-Schmidt-Astrographs very well and know the potential of these optics. So I didn't have to think twice before agreeing to a test. What can be said "Out-of-the-box" about the...
  • RASA 8: Test Report with mit Fujifilm X-T3 - Sebastian Voltmer

    The RASA 8 already proved itself as practical and easy to operate in the first tests. Without annoying mirror shifting I could focus the camera (Fujifilm X-T3) within one minute. Thanks to the very fast f-ratio of the RASA 8, it is even possible to focus on average bright stars in the field of view, without having to point the telescope at a bright star. No collimation was necessary after unpacking and mounting the instrument (the telescope seems to be very resistant against shocks and temperature changes). The star image in APS-C format is perfect down to the corners of the image. Due to the high light intensity, very short exposure times of less than 30 seconds and low ISO values can be used, as...
